The boiler feed pump in our facility can no longer be used. There are four waste heat boilers and a total of 12 pumps; the configuration has been changed from one in use with one as a spare to one in use with two spares. The vibration problem has yet to be resolved – pumps were replaced from Changsha brand to Hualian brand, and then to those from Zhengzhou Power Station, but the issues continued.

I can help you solve the vibration problem by replacing it with a pump from my company. To address this vibration issue, our company has made tremendous efforts; other companies have invested probably less than a quarter of what we have
Boiler pumps are widely used in chemical plants, and there aren’t many problems. The key is to identify the cause of the vibration – whether it lies in the equipment itself, the manufacturing process, or the design and installation It may not lie in which pump to use.
For boiler pumps, that’s definitely the case. As for models 46-50, our company has conducted a thorough analysis of the causes of vibration; we improved the design to address this issue, and now there are no problems anymore
